Patent CA-2271207-A1 (CA)
Inventor: MALPOHL KLAUS
IPC: B22D2/00
Filed: 1997-11-10
Abstract: The invention concerns a metering oven (1) with a vessel (12) for holding a liquid metal and with a device for detecting a liquid metal level in a vessel. A tubular probe (5) is connected to a gas source (10) for discharging a gas at a predetermined pressure from the gas source through the probe and out of its outlet aperture. The probe is spatially associated in a fixed manner with the vessel such that pressures which can be detected by a pressure-measuring device (9) can be associated with different liquid metal levels inside the probe. At a given pressure threshold value, the pressure-measuring device can emit a signal for a given liquid metal level to be detected.

Title: Anonymous voice communication using on-line controls
Inventor: DESIMONE ANTONIO
IPC: H04M7/00
Filed: 1999-06-14
Abstract: A system and method for providing anonymous voice communications using the telephone network under the direction of an on-line data network. A  call broker receives call setup information from on-line session participants, such as chat room participants, after providing callback telephone numbers and, as appropriate, billing information. In one illustrative embodiment, a user (the call initiator) present in a chat room session establishes a data connection to a telephone company site using, e.g., an Internet web browser to establish a Call Broker session. The Call Broker then provides session information (such as a telephone company URL) and a Participant Authorization Code (PAC), which information is passed to a selected chat participant in the current chat room.  When the chosen participant uses the received URL to access the telephone company site, and enters the received participant code and a call-back number, the telephone company completes voice links to the initiator and the selected participant and bridges these links together. Other embodiments permit adding additional parties, and engaging the chat server to negotiates with the Call Broker to establish a PAC that is made available to all chat participants. These and other embodiments of the present invention permit participants in an on-line chat or similar text-based session to retain their anonymity while extending their communications to voice calls.
